packages—all connected to an inkjet printer. PCs were
obtained under a three-year lease from a local supplier.
Many users felt that the lack of sufficient mainframe
software support and lengthy systems development time on
the part of the MIS group had been partially compensated
by the use of PCs. For example, production scheduling in
major work centers in the factory was done with a spread-
sheet on PCs. However, the principal use for many PCs was
as a “dumb” terminal to the mainframe for database inquiry
or sending e-mail. In addition, secretaries and engineers rou-
tinely used PC word processing to write memos. Of the 300
users on Fort Wayne’s mainframe, about 210 were accessing
it through PCs. The remaining users were CAD users.
The division also had powerful personal worksta-
tions for technical work. As of 2002, Fort Wayne had six
IBM workstations used by the development engineering
group for special projects. They were connected through a
local area network (LAN). Several Sun workstations were
also linked into the LAN during the previous year.
Personnel at the Chicago facility used 18 IBM CAD work-
stations for normal production work. At Fort Wayne, there
were also 25 Sun and IBM workstations used for the pro-
duction of drawings.
Drawings made in Chicago on workstations were
stored on Fort Wayne’s mainframe and uploaded and
downloaded over a high-speed dedicated telephone line.
Chicago’s designers liked their CAD stations, but they
were having trouble with the connection between the
mainframe and the Chicago LAN. Tom Goodman, the MIS
support person in Chicago, told Browning, “I feel like we
are the beta site for linking sites together.”


Data Flow and Functional Responsibilities


Exhibit 7 illustrates the generalized data flow among the
main functional areas of the Fort Wayne operation. Of the
seven functions, only the human resources (HR) depart-
ment was not connected to the main information flow. The
remaining six organizational areas participated in a contin-
uous sequential flow of information.
The flow of business information started with the
interaction between marketing and the customer.
Information originated from the customer when a technical
description or specification (a “spec”) was sent to IMT for
a new machine. The length of the spec could be from ten to
several hundred pages. A marketing engineer would then
read the spec and enter his or her interpretation of it into a
mainframe negotiation program. The negotiation program
(MDB), inherited from WILMEC, required the input of
about fifty computer screens of data and was written in
COBOL. For presentations, marketing used Excel and
PowerPoint on their PCs.


If a marketing engineer had a question about a spec,
he or she called a design engineer or another local expert.
Most estimates had to be turned around in 10 working
days. Because of the volume of requests and a staff of only
two engineers covering all of the United States, negotia-
tions were sometimes very hectic. Mike Truelove, a mar-
keting engineer, told Browning, “We do the best we can,
but we miss some things from time to time. Almost always
after winning the order, we go back and negotiate with the
customer over what we missed.”
Another frequently used mainframe application was
a query system (called INFO) automatically linked to data
from the negotiation program. It was used to analyze data
from ongoing negotiations as well as contracts after they
were won or lost.
The administration and finance group was the home
for most business support systems. The purchase order,
accounts payable, and accounts receivable systems were
applications used by purchasing, receiving, and other
groups. All three systems had been custom developed on
the AS/400 by the General Engineering MIS staff (some of
whom now worked at CMCI). Although wages and
salaries were maintained locally, an external data service
company handled the payroll.
As of 2002, human resources used only stand-alone
computers. HR had plans to install a LAN that operated
customized corporate programs for handling HR func-
tions, including benefits and pension/investment plans.
There were no plans to connect the LAN with Fort
Wayne’s mainframe due to security concerns for the confi-
dential personnel records residing on HR’s computers.

Production Requirements
Each machine the company made was electrically and
mechanically custom designed to a customer’s exact spec-
ifications. Customization requirements, when mixed with
the complexities of the economic and engineering limits,
required sophisticated computer programs for modeling
and design work. In 2002, Fort Wayne had three separate
design systems, one for each of the three types of custom
machines. Design engineers for each product line were
experts on their own programs.
The first step in design engineering was to receive
electronically the data previously entered into the negotia-
tion program. The process entailed pulling the data records
from the negotiation database. The design engineer reread
the customer’s spec and decided which additional data
needed to be added to the input files for the design pro-
gram. The program then generated a design that the engi-
neer reviewed in detail and often revised. After the design
was accepted by the engineer, the electronic computer file
